Who is it?
Genus Anguilla
Eels are serpentine fishes with a cylindrical body. They have small scales embedded in their dermis. Their skin is covered by abundant mucus.
In 2019, 19 species of eels have been identified. Genus Anguilla belongs to the Anguilliformes, which is composed of this single genus sub-group. These species live in tempered as well as tropical oceans.
All eels share a similar reproduction cycle. First, larvae are born in the sea and migrate to the continental shelf where they go through morphological changes. Then, they colonize all the freshwater streams. Using this strategy avoids an intra-species competition.

Biotope presentation
The acidification of water comes from the decomposition of plants. This phenomenon changes the color of the water, which tends to turn brown. In some areas particularly rich in organic matter, the water is so dark that it is called "black water".
The australian longfin eel is most often found at a depth between 1m and 3000m. However, it is not impossible to find this species at other depths.
